Terabits (Tb) to Petabits (Pb) Converter
Type your storage value in the input field to find Petabits (Pb) equivalent of your Terabit (Tb) value. 1 Tb = 0.001 Pb, calculated across both decimal (SI) and binary (IEC) standards.

How to Convert Terabits to Petabits
To convert terabits to petabits, divide by 1,000. This gives you the equivalent storage size in the target unit. Learn more: Pb to Terabits converter.
Tb: A terabit is 1,000 gigabits or 10^12 bits. Used for backbone network and data center connections. Try the Terabits to PiB calculator.
Pb: A petabit is 1,000 terabits or 10^15 bits. Used for measuring massive network throughput. Check out our convert GB to Petabits.
1 Tb = 0.001 Pb (using SI decimal standard) — or equivalently, 1 Pb = 1,000Tb.
Tb to Pb Conversion Formula
// Convert Tb to Pb
Pb = Tb × 0.001
// Reverse: Convert Pb to Tb
Tb = Pb × 1,000
Terabit to Petabit Conversion Examples
100 Tb = 0.1 Pb
256 Tb = 0.256 Pb
500 Tb = 0.5 Pb
1,000 Tb = 1 Pb
2,048 Tb = 2.048 Pb
What Is a Terabit?
A terabit is 1,000 gigabits or 10^12 bits. Used for backbone network and data center connections. See also: Gibibits to b.
The terabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our how many KB/s in Megabits Per Second.
Common uses: Data center interconnects, backbone networks, high-capacity optical links Related: how many Bytes in a Tb.
1 Tb = 1 × 10¹² bits = 125 × 10⁹ bytes.
The terabit can be abbreviated as Tb; for example, 1 terabit can be written as 1 Tb.
What Is a Petabit?
